- Cherie loves playing pranks on her younger siblings, although Cherie is very good.
- Cherie's dress was originally going to be deep blue, but it was later changed to dark yellow.
- Cherie often goes for a drive, such as the episode "Dance Class".
- Cherie and her boyfriend Michael seem to be the only animals not to go back home to the Peppaverse, although she sometimes visits and also had her wedding in the Peppaverse.
- Cherie and her boyfriend's models took 17 hours to do even though they were computer-animated. This was because how thick their body figures were. During the animated segment, it was very hard to draw Cherie and her boyfriend's models and took much longer and incorporate them into the episode. Because her wedding dress was so puffy, it took 14 weeks to draw the skirt and sleeves.
- She is very smart.
